Title: Mixing device and method for gaseous, liquid or pulverised solid substances
Inventor: WITTEVEEN GUSTAAF J
IPC: B05B7/10
Filed: 1992-03-19
Abstract: Device for mixing gas, liquids or pulverised solid substances with a gas flow (1), whirling (vortex) around an axis in the flow direction. The whirling gas flow is guided through a converging passage (4) and, during or after being charged with the substance, abruptly widens in cylindrical space (11), as a result of which vortex break down occurs and an exceptionally thorough mixing and/or atomizing of the substance is obtained. Application in a burner improves the combustion result, keeps the NOX-values low and prevents the flame from being blown off.

Patent CA-2118276-A1 (CA)
Inventor: PRAGER KENNETH E
IPC: G06T5/20
Filed: 1994-10-17
Abstract: A scene based nonuniformity correction method (40) that computes and applies offset correction errors to a video signal corresponding to an image derived from a imaging sensor (11). A video signal derived from the sensor (11) is processed such that a vector representing offset correction terms is formed, and this vector is initially set to zero. Each element in this vector represents a correction term for a particular detector of the sensor (11). The vector is applied to each pixel of the image by a processor (13) as the pixels are read from the sensor (11). To measure the offset error, the image is separated into vertically oriented regions, each comprising a plurality of channels. The average of each channel within a region is computed (42), and a set of region vectors is formed, such that there is one region vector for each region. Each region vector is then globally highpass filtered and then edges larger than a predefined threshold are detected (43), and marked (44). Then, each region vector is further separated into sub-regions (45). The isolated sub-regions are locally high-pass filtered. In one embodiment, the correction terms for each vertical region vector are averaged together, resulting in a single correction vector (48). The correction terms calculated for each vertical region may also be applied individually to each detector of the sensor (11). In this second embodiment, the offset level error in each region for each channel is calculated (49), wherein the offset level error at boundary edges is undefined. The correction terms corresponding to a region are applied as the detector (11) scans the scene and views a portion corresponding to that particular region. The correction terms are smoothed at region boundaries to eliminate noise due to boundary in transitions.

Title: Telecommunications terminal block
Inventor: BAUM THOMAS MATTHEW
IPC: H01R4/24
Filed: 1992-10-05
Abstract: Insulation displacing connectors (24) of an "inverted" type extend upwardly from a base (14) of the terminal block (12) into connector chambers (66) of driver modules (50) movable relative to the base (14) between upper and lower positions. Passageways (70) within the modules (50) direct service wires (46) moved through the passageways (70) into the connec-tor chambers (66) and into entrance openings (30) un-derlying upper edge portions (28) of the insulation displacing connectors (24) within the chambers (66).   Movement of the module (50) from its upper position to its lower position drives the service wires (46) downwardly from the entrance openings (30) of the connectors (24) into and through slots (32) underlying the entrance openings (30), to establish electrical con-tact with the service wires (46) and the connectors (24) and, in the case of larger diameter wires, to im-pale the service wires upon impaling elements (34) re-sisting pullout of the wires. Downward movement of a module (50) also establishes conductive engagement between the connectors (24) and tip and ring conduc-tors (76) of an overvoltage limiting element (74). Sea-lant pump chambers (88) within the modules (50) and cooperating sealant pump elements (92) upon the base (14) of the terminal block (12) introduce reserve sealant material (84) into the modules (50) upon movement of the modules (50) from an upper position to a lower position, to eliminate or at least reduce the size of voids in the sealant material (84). A test clip surface (98) upon the module (50) inclines a test clip (94) attached thereto away from an adjacent clip (94). The modules (50) are driven from their upper positions to their lower positions by thread-form-ing fasteners (58).

Abstract: Apparatus and method for auto-self testing of a power converter and motor system wherein the power converter has three parallel legs, each including two series connected gate-turn-off thyristors (GTO) connected between a pair of DC power source buses. A  microprocessor controls the test sequence in which each GTO is individually turned on in a predetermined order so as to create a transient snubber current through the motor and through each GTO when it is turned on. The snubber current and a voltage in each leg is measured and compared to a respective reference to detect wiring errors, and defects in the motor, the GTOs, and other system components. Error messages are generated in response to detection of abnormalities or defects.

Title: Improved methods of using ion trap mass spectrometers
Inventor: WELLS GREGORY J
IPC: H01J49/14
Filed: 1994-04-06
Abstract: Improved methods of using an ion trap mass spectrometer (10) whereby AC voltages supplemental to the AC trapping voltage are used for scanning the trap, for conducting chemical ionization experiments, and for conducting MS experiments, are shown. In one embodiment a broadband supplemental AC voltage is applied to rid the trap of ions above or below a preselected cutoff mass. This is particularly useful in conducting chemical ionization (CI) experiments for eliminating high mass sample ions that are formed when the reagent gas is ionized by electron impact ionization (EI).  Likewise, this technique may be used to eliminate low mass reagent ions when conducting an electron impact ionization experiment in the presence of a reagent gas.

Title: Independently switched voice and data calls using a simultaneous voice and data modem
Inventor: KO KENNETH D
IPC: H04M11/06
Filed: 1995-01-30
Abstract: A central office of a public switched telephone network has a modem pool that includes both simultaneous voice and data (SVD) capable modems and standard, e.g., CCITT V.32 compatible, modems. A user with an SVD modem, i.e., an SVD user, establishes an SVD link with the SVD modem of the central office. These SVD modems exchange SVD signals that include voice and data. The SVD modem of the central office separates the voice and data portions of the SVD signal for separate transmission to different parties. The voice portion of the SVD signal receives standard voice-call handling from the central office for transmission to the party that is a part of the voice call. The data portion of the SVD signal is routed through the standard modem of the central office for transmission to the party that is a part of the data call. As a result, neither of these remote parties is required to have an SVD capable modem ? yet the SVD user has both a voice connection and a data connection over a single "tip/ring" type telephone line.

Title: Method of conducting racing events
Inventor: PAULSON RODNEY L
IPC: A63K1/00
Filed: 1995-02-07
Abstract: A method for conducting racing events begins with the determination of the number of lanes to be utilized in all of the individual races of the overall competition. Each racing competition includes a plurality of individual sprint races preferably equal in number to the predetermined number of lanes being utilized. Each competitor for the entire racing competition is assigned a predetermined speed ranking, and then the competitors are aligned for the individual sprint races. The competitor with the highest speed ranking is aligned in the first lane of the first sprint, and subsequent competitors in order of descending speed ranking are aligned in the first lane of subsequent sprints until the first lane of each individual sprint is filled. The remaining competitors are then aligned in the second lane of each sprint, again in descending speed ranking order. Any subsequent lanes are aligned in the same fashion. Each of the individual sprint races are then conducted with the first competitor in each sprint designated a sprint winner. The time of each sprint winner is recorded in each individual sprint, and compared with the times of the other sprint winners to determine the competition winner.
